DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] The utility model adopts a solid suspended matter removal device for primary sewage treatment, such as Figure 1 As shown, the upper surface of the bottom plate 1 is fixedly connected with a main filter box 2 and a secondary filter box 3, and the main filter box 2 and the secondary filter box 3 are connected by a hard water pipe 15. The sewage first flows into the main filter box 2 and then flows into the secondary filter box 3 through the hard water pipe 15. The main filter screen 4 is transversely fixedly connected inside the main filter box 2. The main filter screen 4 mainly filters large-caliber suspended solids. A suction pipe 6 is fixedly connected to one side of the main filter box 2, and a water pump 5 is fixedly connected to the bottom end of the suction pipe 6. The top of the main filter box 2 is rotatably connected to a box cover 10, and the surface of the main filter box 2 away from the suction pipe 6 is fixedly connected to Two electric push rods 11, a transmission rod 14 is fixedly connected between the two electric push rods 11, a second motor 13 is fixedly connected to one side of the two electric push rods 11, a driving plate 9 is hinged at the output end of the two electric push rods 11, and the driving plate 9 is fixedly connected to the upper surface of the box cover 10. When the motor is started, the two electric push rods 11 move downward to pull up the box cover 10 through the driving plate 9, which increases the speed and saves labor. Two water outlet pipes 21 are fixedly connected to the side of the auxiliary filter box 3 away from the hard water pipe 15, and a water stop valve 23 is provided at one end of the two water outlet pipes 21 close to the auxiliary filter box 3.

[0022] like Figure 2 As shown, the auxiliary filter box 3 is fixedly connected to a double-headed motor 20 on one side of the water outlet pipe 21, and the two output shafts of the double-headed motor 20 are fixedly connected to a threaded rod 25, and a slider 19 is threadedly connected to the threaded rod 25. The lower end of the slider 19 is fixedly connected to an auxiliary filter screen 22. The auxiliary filter box 3 is provided with a slide groove on one side of the water outlet pipe 21. When the double-headed motor 20 is started, the slider 19 will move on the threaded rod 25 due to the action of the limit rod 18, thereby driving the auxiliary filter tank to move for replacement. One end of the upper surface of the base plate 1 is fixedly connected to a support rod 7.

[0023] like Figure 2As shown, a fixed block 16 is fixedly connected between the double-headed motor 20 and the auxiliary filter box 3, and baffles 17 are fixedly connected at both ends of the threaded rod 25 to prevent the slider 19 from detaching from the threaded rod 25. A limiting rod 18 is fixedly connected to one side of the slider 19, and one end of the limiting rod 18 is embedded in the slide groove and slidably connected to the slide groove, and a cross bar is fixedly connected to the upper end of one side of the support rod 7.

[0024] like Figure 1 As shown, it is characterized in that a fixing sleeve 8 is fixedly connected between the cross bar and the water pumping pipe 6, and an engaging groove is provided on the water outlet pipe 21, and the slider 19 is moved laterally by the limiting rod 18.

[0025] like Figure 3 As shown, the auxiliary filter 22 is directly opposite to the fitting groove, and a rubber sheet 24 is fixedly connected around the inside of the fitting groove. When the auxiliary filter 22 is replaced, the rubber sheet will recover from the squeezed state after the auxiliary filter 22 is moved away to prevent the sewage from flowing out.

[0026] like Figure 2 As shown, one side of the slider 19 is fixedly connected to the limiting rod 18, and one end of the limiting rod 18 is embedded in the sliding groove and slidably connected to the sliding groove.

[0027] Working principle: When in use, first turn on the water pump 5, and the sewage is transported to the main filter box 2 through the suction pipe 6. The sewage first passes through the main filter screen 4 to screen out large-diameter suspended matter. When the large-diameter suspended matter accumulates too much, turn on the second motor 13, and open the box cover 10 under the action of the electric push rod 11 to clean up the large-diameter suspended matter. After the cleaning is completed, the box cover 10 is closed through the action of the second motor 13 and the electric push rod 11, and then the sewage flows along the hard water pipe 15 to the auxiliary filter box 3, and the sewage flows out from the water outlet through the auxiliary filter screen 22. When the small-diameter suspended matter accumulates too much, the sewage will be discharged from the water outlet. When there is too much accumulation of matter, the water stop valve 23 can be closed and the box cover 10 can be opened by the second motor 13 and the electric push rod 11 to clean up the small-caliber suspended matter. At the same time, the double-headed motor 20 can be turned on, and the two sliders 19 can be moved to one side as a whole under the action of the limit rod 18 and the slide groove. Because the auxiliary filter 22 is fixed under the slider 19, the auxiliary filter 22 will move horizontally with the slider 19, so the auxiliary filter 22 can be replaced and the used auxiliary filter 22 can be cleaned, which solves the problem of the auxiliary filter 22 being blocked and improves work efficiency.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
